Product Details

USWF-PP30-2045 is a 30 micron 20"x4.5" pleated polyester sediment replacement filter that is proudly manufactured in the USA. It is made from FDA Title 21 compliant polyester fabric pleated around a polypropylene core to provide a high quality filter independently tested to NSF / ANSI standards 42, 61, and 372.
Pleated filters offer the lowest pressure drop and highest flow rate of all sediment filter types by providing as much filtration surface as possible to maximize water flow. However because pleated filters offer no filtration gradient or depth they are best suited to filter sediment of uniform particle size.
USWF only carries pleated polyester filters. The synthetic filter media is bacteria resistant so that it can be used on both treated and untreated water supplies. The pleated polyester is also highly durable meaning that you may rinse and clean the filter once it becomes clogs to extend the filter life.
This American made filter is a compatible replacement for other popular pleated sediment filters like the Pentek R30-20BB, Hydronix SPC-45-2030, and more.
Proudly made in America

Choosing American-made products means investing in quality you can trust, while also supporting jobs and communities across the United States.

Frequently Asked Questions

What is the micron rating of the USWF 20x4.5 Pleated Polyester Sediment Filter, and what does it remove?

The USWF 30 Micron 20"x4.5" Pleated Polyester Sediment Filter has a 30-micron rating, making it ideal for removing larger sediment particles such as sand, silt, rust flakes, dirt, and scale from your water supply. Its pleated polyester design provides a greater surface area compared to standard spun filters, allowing for higher dirt-holding capacity and improved flow rates. This filter is best used as a pre-filter to protect downstream filtration equipment and plumbing fixtures.

What are the exact dimensions and housing compatibility for this USWF sediment filter?

This USWF filter measures 20 inches in length and 4.5 inches in diameter (often referred to as "Big Blue" size). It is compatible with any standard 20" x 4.5" whole house filter housing, including Pentek Big Blue, Pentair, Culligan HD-950A, American Plumber, and similar-sized systems. Always verify your housing's inner dimensions before purchasing to ensure a proper fit and seal.

How long does the USWF 30 Micron Pleated Polyester Sediment Filter last?

The USWF 20x4.5 Pleated Polyester Sediment Filter typically lasts 6 to 12 months, depending on your water quality, sediment load, and household water usage. In homes with heavy sediment or well water, replacement may be needed sooner—every 3 to 6 months. A key advantage of pleated polyester media is that it can be rinsed and reused in some cases, extending its usable life compared to melt-blown or spun polypropylene alternatives.

Is the USWF Pleated Polyester Sediment Filter washable and reusable?

Yes, one of the standout features of the USWF pleated polyester design is that it is washable and reusable. When flow begins to decrease, simply remove the filter from the housing and rinse it with clean water to dislodge trapped sediment. This can be done multiple times before replacement is necessary, making it a cost-effective and environmentally friendly choice compared to single-use sediment cartridges.

What is the recommended flow rate and temperature range for this USWF filter?

The USWF 30 Micron 20"x4.5" Pleated Polyester Sediment Filter supports flow rates up to approximately 8–10 GPM (gallons per minute), making it suitable for whole-house applications. It operates within a temperature range of 40°F to 145°F (4°C to 62°C) and handles working pressures up to 125 PSI. For optimal performance, pair it with a finer-micron post-filter (such as a 5-micron carbon block) to address taste, odor, and smaller particles.
